Yes , just the same as steel - otherwise the rebar would crack structures !
it moves Because almost all Elements expand when heated and contract when cooled. As you are welding the metal at that location is trying to expand because of the heat. Ahead of the weld area the metal isn't moving. Behind the weld area the metal is trying to contract as it cools. If the whole weld could be heated at once it would expand then contract at the same rate without distortion.
All things expand when they are heated. Gases expand the most, liquids less than gasses, and solids expand the least. Yes they do. Take metal for example it expands when it gets hot.
To allow for the expansion of heated thot water
Actually, nothing is heated to create cement. Cement is a mechanically bonded combination of cement, sand, water, and gravel (aggregate).
Water atoms do not expand or multiply when heated. When water is heated, the heat energy causes the water molecules to move faster and farther apart, which results in the expansion of the water volume. The number of water molecules remains the same.
No, not all objects expand when heated. Most objects do expand when heated, but there are exceptions such as water between 0°C and 4°C, which contracts when heated. The expansion or contraction of an object when heated depends on its material properties.
All liquids expand when heated. e.g. Mercury in a thermometer. One exception may be water when heated form 0 to 4 degrees Celsius.
What size cistern what temp
Gases expand the most when heated compared to solids and liquids. This is because the particles in a gas have more kinetic energy and move more freely than particles in a solid or liquid, allowing for greater expansion when heated.
poo
NO, it is the opposite. remember molecules expand when heated
the process is called gelatinization- which occurs when heated starch molecules absorb water and expand. sometimes they expand 2-3 times their volume when cooked.
Yes, sea water expands when heated because the heat causes the water molecules to move faster and spread out, increasing the volume of the water.
Heat = expansion. The water molecules expand when heated. The container will expand, and then the measurment will be off?
Oil does expand when heated and contracts when cooled.
They will expand by the same percentage, but that percentage, of course, results in more actual length of expansion on the longer object.
